 ## pandoc 2.13 (2021-03-21)
 
-  * Fix fallback to default partials when custom templates are
-    used.  If the directory containing a template does not
-    contain the partial, it should be sought in the default
-    templates, but this was not working properly (#7164).
+  * Support `yaml_metadata_block` extension for `commonmark`, `gfm` (#6537).
+    This supported is a bit more limited than with pandoc's
+    `markdown`.  The YAML block must be the first thing in the input,
+    and the leaf notes are parsed in isolation from the rest of
+    the document.  So, for example, you can't use reference
+    links if the references are defined later in the document.

   * Handle `nocite` better with `--biblatex` and `--natbib` (#4585).
     Previously the nocite metadata field was ignored with these formats.
